This may be a radical idea, but what have you got to lose ?

There's stuff in the playground. From what I read before, it's just an analog signal. It seems to be easier if you have it on a pre-made breakout board.

BUT..... it also seems that it's up to the user to choose the resistor in the other side of the divider, bit of a trade off between accuracy and sensitivity.
